Abstract

Procédé de désulfuration des gaz de carneau dans lequel le produit de fond liquide provenant de la tour à garnissage subit une oxydation forcée dans un réservoir de réaction/d'oxydation. Par la suite, le produit de fond oxydé est envoyé à un hydrocyclone pour être séparé en une surverse contenant une suspension aqueuse composée surtout de fines, de cendres volantes, et de réactif inutilisé, et en une sousverse contenant de manière prédominante une suspension de plâtre. La surverse est subséquemment retournée ou recyclée à la tour à garnissage, tandis que la sousverse est asséchée pour récupérer le plâtre.
